We refer to different views of data as the display mode. File Manager® editor provides three different display modes for data stored in various resources:
Formatted/Table mode displays records in a table using a specified template or copybook. Each column in the table represents a filed within the currently selected layout of the template being applied for the current edit session. This mode allows the user to view and manipulate records in a formatted mannger. The typical usage of the formatted display mode is to manipulate binary data of types which are difficult to manipulate by hand.

Character mode display records in text format. The text displayed is derived from the binary data stored in the specified resource in the current edit session, and interpreted according to the encoding specified when the editor is invoked. Character mode provides a user experience similar to that of typical text editor, with a few aspects modified to suit the mainframe environment.

Because of the inherited restriction of what can be done to records stored in a resource on z/OS® environment (e.g. record length, INPLACE edit, ordering etc), we provide a comprehensive indication when something is not valid according to the characteristics of the resource being edited. See the picture below as an example. The screen shot was taken during an edit session of a KSDS data set with INPLACE edit option.

As you can see in the picture, a line which contains more data than what the underlying record can hold is highlighted as errors (red foreground with grayed background). The lines 11 and 12 are also highlighted as errors due to "invalid insertion", because insertion of new records is not allowed in INPLACE edit mode.
When you try to validate the current editor contents, the editor provides information as to whether any errors exist in the current edit session. See the dialog box below. At this point, the user has the option to review the error(s) and can choose to either:

If you choose to ignore errors and proceed, the editor will attempt to fix the error automatically:
Single Mode Display is implemented using the Eclipse Properties view. Depending on the selection in the editor (both Formatted and Character mode), it displays information about the selected record in a single mode display.
Single mode display provides two different views of the selected record. Namely, Single Mode, which displays fields which are defined in the currently selected record, and Dump Mode, which displays hex and the corresponding character values for the currently selected record.
The current implementation only allows you to view data (no editing or update via Single Mode or Dump Mode is available).
